iTunes merging music
Hi,
I have one music library on my mac mini iTunes and another on my macbook iTunes. Both iTunes are under the same account. These libraries never used to merge until now. Suddenly, the iTunes library on the mac mini is also showing my songs from macbook, but with a cloud and down arrow next to them. I do not want this and want to keep them separate as before. Can someone please help and tell me what I did wrong? Thanks
Sam
